My average since getting my GT with 21" wheels which included last summer in Phoenix running max AC is 3.2 m/kWHr. Last 1000 miles with cooler weather was 3.4 m/kWhr. I drive the way I want traffic permitting, usually in Swift mode. I have tried to drive for better efficeincy but the temptation to hit the electron pedal at a stoplight or on a freeway on ramp is too great for me to resist. I am happy with efficiency.
I have taken multiple several hundred mile trips and calibrated ABRP to match my driving. I use 3.68 m/kWhr at 65 mph reference, 115% of speed limit with a max speed of 85. It works for me and my driving style.
